HEATER AND RADIATOR.

Specification of Letters Patent.

ROBERT w. HABIDIE, or HARTSDALE, NEW YORK.

Patented Ma 22, 1917.

Application filed October 6, 1916. Serial No. 124,191.

To all whom it may concern:

Be it known that 1, ROBERT W. HAnnIn, a citizen of the United States, residing at Hartsdale, in the county of Westchester and State of New York, have invented new and useful Improvements in Heaters and Radiators, of which the following is a specifica- This invention relates to a device for moistening the air of a room or building, and is particularly adapted for use in the rooms of buildings. used for dwelling purposes such as houses, apartments and hotels, as well as in buildings and ofiices used for business purposes, and the object thereof is to provide a device for heating water in a facile and economical manner while exposed to the atmosphere so as to permit the heat from said water to radiate into the atmosphere. of the room or inclosure, 1n which the device is us ed in the form'of vapor of water, to heat and humidify the atmosphere.

further object to provide means for aiding in carrying away from the heater the vapor of water given off thereby.

, device of the character further aims to provide a described, that shall be simple in construction, strong, durable and .eliicient in use, readily attached to the heating plant of a building, and inexpensive to manufacturers.

'VVith the foregoing and other objects in The invention view, the invention consists of the novel con struction, combination and arrangement of parts hereinafter more specifically described,

bodiment of changing and illustrated in the accompanying drawings, wherein is shown the preferred emthe .invention, but it is to be understood that changes, variations and modifications may be resorted to without the scope of the invention.

In describing the invention in detail, reference is had to the accompanying drawings which form a part of this specification and wherein like reference characters denote corresponding parts throughout, the several views','and in which- Figure 1 is a and radiator embodying my invention,

Fig. 2 is a plan ofthe device shown in Fig. 1 with the hood removed,

Fig. 3is a vertical longitudinal section taken on the line 33 of Fig.2, and

Fig. 4 is a vertical cross section taken on the line H of Fig. 1.

The invention has for a front elevation of a heater As illustrated in the drawings, a receptacle adapted to hold-water is provided, comprising a base or bottom, 4, and side walls, 6 extending upward therefrom, connected by corresponding end walls.

Within said receptacle a heating member is provided comprising one or more horizontal conduits, 1, communicating interiorly with chambers 2, formed at opposite walls of said receptacle, one of said chambers is provided with an inlet aperture 3, adapted to receive a supply pipe connection. {is illustrated in the drawings, is shown with a single pipe connection, for. use in a one pipe heating system.

lVhen the device is used with a two pipe heating system, a similar pipe connection may be made with the chamber at the opposite wall of the receptacle.

By means of such construction steam or hot water entering the heating member through the inlet pipe passes into the chamher-,2 connected with said pipe and is by said chamber conducted into the conduits, 1,

and from said-conduits into the opposite chamber 2, thereby distributing the heat given off by said conduits, into the water placed within the receptacle and providing for a free and even circulation of the heatmg medium, within the heating member.

Such construction moreover provides for another and very important result, in that thereby the receptacle may have a maximum area of water exposed to the drying'power of the atmosphere in addition to the heat unlts imparted to the water in the receptacle from the conduits, and at the same time expose to the atmosphere a maximum area of water as a heat radiating medium, much more powerful than an equal area of metal. The heating member moreover enables those conditions and results to be accomplished and maintained by providing for a proper apportionment of the heat radi ating surface to evaporate thedesired quantity of water in the receptacle, without causing an excessive. quantity of vapor to arise from the surface of the water. The

chambers 2, perform a double function; the

one nearest the supply pipe serving as an inlet and distributing chamber, and the opposite one as a draining chamber in which the device and with the bottom of the receptacle, the walls of said conduits extending upward therefrom so as to extend into the water placed in said receptacle and deliver heat from said walls into the water. The bottom of said conduits should be as high as the from said receptacle water'above a predetermined depth.

The heating medium within the heating member may be of such a temperature as to cause a rapid heating and evaporation of the water in the receptacle and supply the atmosphere with vapor of water to a considerable extent. In order that such vapor may not condense on the walls adjacent to the device, a hood is provided having a top plate 8 that protects the air above the water in the receptacle from a cool draft of air or current, and also serves as a deflecting plate to direct said air forward, and out of the front of the heater so that it will become dif-' fused with the air in the walls thereof.

The hood is also provided with a flange 9 extending downwardly from the rear por tion of the top plate 8 below the top or upper edge of the wall of the receptacle to prevent a backward movement of the vapor of water against the walls of the room. The flange 9 is preferably continued forward so as to protect the ends ofv the receptacle against vapor of water passing out from said ends. The flange 9 is offset or spaced from the rear wall of the receptacle so as to leave room for air to pass upward between the rear wall of the receptacle and the flange of the hood. The hood may be mountthe room away from ed upon the receptacle by means of supports 10 attached at their upper ends to the hood, their lower ends engaging sockets 11 formed on the walls of the receptacle, or in any other suitable manner.

When the device is in use and a heating medium is applied to the heating member, the Water in the receptacle becomes heated and vaporized and the air above said receptacle inclosed by said hood becomes of a higher temperature than the adjacent air of the room, and as the cooler air at the back and sides of the receptacle descends it forces the warmer air up between the receptacle and flange of the hood, across the receptacle and out-the front opening or space between the receptacle and the upper plate of the hood laden with moisture or vapor of water toward the center of-the room in which the device is used, thereby enabling the vapor of water produced by the device to become diffused throughout the room and raising the percentage of humidity in the air of the room. The device is especially designed to be used in dwelling houses, apartments and buildings used for business purposes where steam and hot water heat are used to heat the building, so as to overcome the deficiency in humidity in the air of places so heated, and the injurious and uncomfortable conditions caused by a lack of sufiicient humidity in the atmosphere of rooms so heated,

What I claim is In a heater and radiator, an open-topped receptacle, the interior surface of its bottom being formed with transverse chambers at the ends-of the receptacle and with a plurality of. longitudinal conduits communicate ing with said chambers, one of said cham-' bers being provided with an inlet aperture.
